Review, critique, and synthesis of personality theory in motivation to sexually assault

A widely-cited meta-analysis of recidivism amongst adult male perpetrators or sexual assult [Hanson and Bussiere, J. Consult. Clin. Psychol. 66 (1998) 348–362] found that the presence of any personality disorder (APA, Diagnostic and Statistical Manual of Mental Disorders: DSM-III-R. (1987); [APA, Diagnostic and Statistical Manual of Mental Disorders: DSM-IV (1994)] was the only variable to significantly predict sexual recidivism in a category measuring “Psychological Maladjustment” (r₊=.16, n=315). The relationship between personality disturbance and new sexual offenses is undoubtedly a dynamic relationship that deserves exploration. This review and critique of theory covers two theories of personality: (1) a psychoanalytic theory of rapist personality offered by Groth [Men Who Rape: The Psychology of the Offender. (1979), New York: Plenum] and (2) a general biosocial theory or personality disturbance offered by Millon [Disorders of Personality: DSM-IV and Beyond. (1996). New York: Wiley]. Theory offered by Groth is critiqued and limitations considered. Theory offered by Millon is offered and the two approaches are synthesized to suggest possible causes of characteristic psychological disturbance associated with perpetration of sexual assault. Applications for research and practice are considered, and implications of this line of research for risk assessment and sexual assault prevention are reviewed.
